GENERATOR PREPARATION
AUTO FUEL SELECTION
Your generator is equipped with Auto Fuel Selection Technology. What this means is that the generator will auto-
matically select the fuel source (LPG or gasoline) depending on availability. LPG is prioritized; this means that if a
propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is con-
nected, or if there is not enough LPG remaining in the tank, the generator will use gasoline (if there is gasoline in the
fuel tank). Refer to Table 1 below for information on how to set up your generator for a particular fuel.

Table 1 – Auto Fuel Selection® chart.*It is ideal to run the generator on LPG with the fuel valve closed (OFF), but if
it stays open (RUN), the generator will still run properly.
NOTE: Make sure the generator can handle the load(s) you plan to connect. The generator can provide more power
when running on gasoline than on LPG. Consult the specifications table on p. 3, as well as page 23 ("Calculating the
Wattage of Your Device(s)") to ensure that your load(s) will not exceed the rated wattage for a particular fuel. See
also "Switching Fuels" (p. 25) for more information.
STEP 3 - CONNECT THE BATTERY
WARNING! Use only genuine WEN batteries with your generator (part no. 56380i-1304). Use of other bat-
teries may induce premature product failure and could pose a safety risk.
ABOUT THE BATTERY
1. The lithium-ion battery supplied with your generator is only partially charged, in order to maximize its service
life. The battery may not have enough charge to start the engine during its first use. If this is the case, connect the
battery according to the instructions below, and start the generator using the recoil starter, according to the instruc-
tions below. The battery will receive charge when the generator is running.
2. Lithium-ion batteries are subject to a natural aging process. The battery must be replaced at the latest when its
capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery are no longer capable of meet-
ing the high power requirements needed for the proper operation of your generator, and therefore pose a safety risk.
3. DO NOT INCINERATE BATTERY. Do not throw the battery into an open fire as this poses a risk of explosion. Do
not ignite the battery or expose it to fire.
4. AVOID DAMAGE AND SHOCKS. Immediately replace batteries that have been dropped from a height of more than
one meter (3 feet) or those that have been exposed to violent shocks, even if the housing of the battery appears to
be undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please
read the waste disposal information on p. 38 for proper battery disposal.
5. DO NOT CRUSH, DROP OR DAMAGE BATTERY. Do not use the battery if it has sustained a sharp blow, been
dropped, run over or has been damaged in any way (e.g. pierced with a nail, hit with a hammer, stepped on, etc.).
6. DO NOT DISASSEMBLE. Incorrect reassembly may pose a serious risk of electric shock, fire or exposure to toxic
battery chemicals. If battery or charger are damaged, call WEN customer service at 1-800-232-1195 for assistance.
7. DO NOT SHORT CIRCUIT. Batteries will short circuit if a metal object makes a connection between the positive
and negative contacts on the battery. Do not place the battery near anything that may cause a short circuit, such as
paper clips, coins, keys, screws, nails and other metallic objects. A short-circuited battery poses a risk of fire and
severe personal injury. NOTE: The safe temperature range for charging the battery is 25°F – 104°F.
The generator is shipped with the lithium-ion battery's negative (-) terminal disconnected to maximize safety. To
start the generator using electric start, the battery must be connected.
